I would if it wasnt blocked in my god damn country.

Also, old school metalcore is ****ing awesome and actually sounds like what the name implies. Should we blame killswich engage's melodic metalcore for killing metalcore?

Pretty much. I guess Poison the Well's sound was a starting point for that as well, even if they don't really sound like Killswitch or Bullet for My Valentine. Unearth would also have a pretty good claim to being the second most important band after Killswitch in ruining metalcore.

Lest you not forget Underoath.

Indeed. But let us also not forget their first two albums.

Unblack Metal?

Basically. I see their first two albums as a post-hardcore version of Emperor. I don't even really like Emperor, but Underoath were amazing.
